Description

Technical Field

[0001] The invention relates to the technical field of tool swing detection, in particular to an automatic precision tool swing detector. Background Art

[0002] Tool swing refers to the deviation between the tool running diameter and the tool standard diameter caused by various reasons such as the machine tool spindle or tool when the tool moves. The common method of measuring tool swing is to use the tool swing detection table to point on the diameter of the rotating tool. The difference in the calibration table reading is the swing number. As long as the tool swing number is known, the program can be modified or the tool clamping can be adjusted to achieve accurate processing according to the workpiece data.

[0003] With the existing external tool swing detection device for CNC tool machines, after the tool is hung on the CNC machine, the tool swing detector is placed close to the CNC, and the detection table of the tool swing detector is close to the tool. The head of the detection table contacts the tool, and after driving the CNC spindle to rotate, the pointer of the detection table begins to swing, and the difference in the calibration readings is the swing number, thereby achieving the effect of detecting the tool swing.

[0004] The drawback of this knife swing detection method is that the knife swing detection takes up the operation time of the machine, which consumes a long time and delays the working efficiency of the machine, thereby reducing the output value of the machine.

[0005] Based on this, the present invention designs an automatic precision tool swing detector to solve the above problems. Summary of the invention

[0010] Preferably, three mounting rods are equidistantly arranged in the mounting groove, and the angle between the center points of the three mounting rods is 120 degrees.

[0011] By adopting the above technical solution, the angle between the three mounting rods is 120 degrees, which provides more uniform support for the support tube and reduces space waste.

[0012] Preferably, the support tube is fixed to the rotating rod in a threaded connection manner.

[0013] By adopting the above technical solution, when a different support cylinder type needs to be replaced, the support cylinder is removed from the rotating rod and replaced with the required support cylinder, which is convenient for adapting to tool detection of different sizes.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] Reference Figure 1-Figure 6, an automatic precision tool swing detector, comprising an installation box 1, a support tube 3 for placing a tool 2, a tool swing detection table 4, and a support seat 5 fixedly arranged in the installation box 1, a mounting groove 6 is opened on the support seat 5, a rotating hole 7 is opened at the bottom of the installation groove 6, a rotating rod 8 is rotatably arranged in the rotating hole 7, and a driving device for driving the rotating rod 8 to rotate is arranged on the installation box 1. In this embodiment, the rotating rod 8 is driven to rotate by a motor 9; the support tube 3 is coaxially threadedly connected to the rotating rod 8, the support tube 3 is in a truncated cone shape, a fixing plate 10 is fixedly arranged on the support seat 5, a bearing 11 is rotatably arranged on the fixing plate 10, the support tube 3 is plugged into the inner ring of the bearing 11, and the support tube 3 is rotated on the installation box 1;

[0031] Reference Figure 1-Figure 6 A placing rod 12 is arranged on the fixing plate 10, a mounting block 13 is arranged on the placing rod 12, a moving block 14 is slidably arranged on the mounting block 13, a fixing component for fixing the moving block 14 is arranged on the mounting block 13, and a tool swing detection table 4 is fixedly arranged on the moving block 14; before the detection, the tool 2 is vertically placed in the supporting cylinder 3, and the inner wall of the supporting cylinder 3 supports the tool 2, and the moving block 14 is adjusted to move the tool swing detection table 4 toward the side of the tool 2 until the detection head of the tool swing detection table 4 contacts the tool 2, The moving block 14 is fixed by a fixing component, and then the motor 9 is driven to rotate the rotating rod 8, thereby driving the supporting cylinder 3 to rotate, thereby driving the tool 2 to rotate. At this time, the tool swing detection meter 4 detects the tool 2. When the pointer deviation value of the tool swing detection meter 4 is not within the specified range, it indicates that the tool 2 has a defect. The tool 2 is detected in advance by the tool swing detection device, and there is no need to start the CNC for detection. The process is fast and simple. The tool 2 is detected in advance, thereby reducing CNC downtime and achieving the effect of improving work efficiency.

[0032] Reference Figure 1-Figure 6 A fixing block is fixedly arranged on the groove wall of the mounting groove 6, and a mounting rod 15 is fixedly arranged on the fixing block at an angle, and a supporting wheel 16 is rotatably arranged on the mounting rod 15. Two supporting wheels 16 are arranged on the mounting rod 15, and the upper and lower supporting wheels 16 respectively abut against the supporting tube 3. A plurality of mounting rods 15 are arranged in the mounting groove 6. In this embodiment, three mounting rods 15 are evenly arranged in the mounting groove 6, and the angle between the center points of the three mounting rods 15 is 120 degrees; when the supporting tube 3 rotates, the six supporting wheels 16 respectively support the supporting tube 3, reduce the swing of the supporting tube 3, and improve the accuracy of the detection. The angle between the three mounting rods 15 is 120 degrees, which supports the supporting tube 3 more evenly and reduces the waste of space and resources.

[0033] Reference Figure 1-Figure 6When it is necessary to replace a different type of support tube 3, the support tube 3 is removed from the rotating rod 8 and the required support tube 3 is replaced, which is convenient for adapting to the detection of tools 2 of different sizes; a debris groove 17 is opened on the rotating rod 8, and the debris groove 17 is located in the support tube 3. The debris groove 17 is located below the tool 2. The debris generated during the detection falls downward into the debris groove 17 for collection, thereby reducing the impact of residual debris accumulation on the placement of the tool 2.

[0034] The implementation principle of this embodiment is: before detection, the tool 2 is placed in the support cylinder 3, and the moving block 14 is pushed at the same time to make the tool swing detection head contact the tool 2. During detection, the motor 9 is driven to drive the rotating rod 8 to rotate, thereby driving the support cylinder 3 to rotate. At this time, the support wheel 16 supports the support cylinder 3 to prevent the support cylinder 3 from swinging. The support cylinder 3 stably drives the tool 2 to rotate. At this time, the pointer on the tool swing detection table 4 swings. When the pointer swings beyond the specified range, it indicates that there is a defect on the tool 2. The tool 2 is pre-detected by the tool swing detection device without turning on the CNC for detection. The process is fast and simple. The tool 2 is detected in advance, thereby reducing CNC downtime and achieving the effect of improving work efficiency.
